I am sorry to hear your experience with ETrade was extremely negative. I must admit I experienced some frustration. I signed up for two US$10K accts w/c qualified me 20K mi. Etrade originally credited only 15K mi, but I did get the 20K mi properly credited to my UAL mileage plus acct with an add'l 5K mi.

My suggestion, tell etrade you no longer can stay with them if the mileages are not properly credited to your UAL acct.
